Proposes an educational model for chemistry PhD education that emphasizes productivity and centrality of research. Supports greater development of communication skills and suggests a four-year timeline. Listed is a curriculum usable for most sciences. (ML)

Recommends determining molecular weights of liquids by use of a thermocouple. Utilizing a mathematical gas equation, the molecular weight can be determined from the measurement of the vapor temperature upon complete evaporation. Lists benefits as reduced time and cost, and improved safety factors. (ML)

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Describes a molar volume-molar mass experiment for use in general chemistry laboratories. Gives background technical information, procedures for the titration of aqueous hydrogen peroxide with standard potassium permanganate and catalytic decomposition of hydrogen peroxide to produce oxygen, and a discussion of the results obtained in three…

Presents the academic and industrial perspectives on the need for additional emphasis on safety. Outlines one approach for teaching a safety-related course including five video sessions on a brief description; safety equipment and procedures; inspection of laboratory area; safety experiments; and reviews. (RT)

Describes a graduate course designed to teach the noncrystallographer how to read a structure paper critically. The course combines formal didactic instruction with student seminar presentations of specific papers from the crystallographic literature. Includes a course outline. (CW)

Describes a purification process through affinity chromatography necessary to obtain specific blood group glycoproteins from erythrocytic membranes. Discusses the preparation of erythrocytic membranes, extraction of glycoprotein from membranes, affinity chromatography purification, determination of glycoproteins, and results. (CW)

Explains gyroscopic motions to college freshman or high school seniors who have learned about centripetal acceleration and the transformations of a couple. Contains several figures showing the direction of forces and motion. (YP)

Presented are two case reports about an instructional experiment. "Peer Perspectives" uses nonspecialized faculty to experience some aspects of an introductory course for providing perspective, insight, and feedback to those who wish to make their courses more appropriate to nonmajors. (YP)

Presented are two case studies on the perspective of the history of science. Provided are the contributions of 12 famous scientists with their historical illustrations and diagrams. Five conclusions are drawn from these studies. (YP)

Reports the results of a radioactivity survey in England. Discusses the aim of the survey, experimental procedures, analysis, and results. Shows several diagrams, graphs, and tables. (YP)

Examines the problem-solving strategies of experts and novices. Summarizes the overall performance of four experts and eight novices. Examines several protocols in depth in order to show how subjects introduced new terms and relationships during problem solving sessions. Compares the strategies of expert and novice problem solvers. (CW)

Introduced are 20 places for field trips throughout the United States. Included are the location, explanation, famous things, and references for each place. (YP)

Reports on a study using two alternatives for evaluating the quality of teaching and courses in an undergraduate engineering program. Results indicate that the relationship between a global problem and individual questions is highly correlated. (TW)

Describes an evaluation program which is aimed at providing well-designed, comprehensive, and objective tests to a specific category of engineering students. Involves the use of a computerized statistical analysis. Provides recommendations for organizing such an activity. (TW)
